I have a male yorkie and I agree with the comments thus far...he is very affectionate, loves to be with you all the times, I call him my shadow sometimes.
With the humping - that was a concern of mine also but once he was neutered, he hasn't really hump anything except his stuffed animal once.
With male dogs, they do mark though, I have found that Duke marks outside and have marked inside after he was neutered. But again like someone mentioned before, if it's your dog, they can do no wrong so go and play with a few to see which one catches your attention.
